Overview
PCA9515 I2C-bus repeater Rev.
09 — 23 April 2009 Product data sheet 1.
General description The PCA9515 is a BiCMOS integrated circuit intended for application in I2C-bus and SMBus systems.
While retaining all the operating modes and features of the I2C-bus system, it permits extension of the I2C-bus by buffering both the data (SDAn) and the clock (SCLn) lines, thus enabling two buses of 400 pF.
The I2C-bus capacitance limit of 400 pF restricts the number of devices and bus length.
Using the PCA9515 enables the system designer to isolate two halves of a bus, thus more devices or longer length can be accommodated.
It can also be used to run two buses, one at 5 V and the other at 3.
3 V or a 4...
